It may be convenient and cost effective to share the human shampoo with your Chihuahuas. However, it may have costly consequences that you want to know.
Human Skin and Dog’s Skin – pH Level
The pH level (or acidity level) of human skin is very different to that of dog skin. According to petmd.com, the human skin has pH level of around 5.2 to 6.2 which is on the acidic side while the pH level of dog’s skin is toward alkaline level ranging between 5.5 and 7.5.
“if a shampoo that is formulated for human skin is used on a dog, the dog’s acid mantle will be disrupted, creating an environment where bacteria, parasites, and viruses can run rampant. Unknowingly, many pet owners will repeat washings of their dogs because of the smell caused by a proliferation of bacteria, making the problem worse as the skin’s acid mantle/pH level becomes more imbalanced. Additionally, if the shampoo makes the skin feel dry, your dog will scratch at its skin, creating abrasions for bacteria to invade. It quickly becomes a vicious cycle…”
